POLE REINFORCEMENT DEVICE 7 Filed Oct. 21, 1940 2 Sheets-Sheet 2 INVENTOR ATTORNEYS Patented Aug. 24, 1943 UNITED STATES FA'I'ENT OFFICE POLE REINFORCEMENT DEVICE. 5 Jewell W. Vanderveer, Erie, Pa. Application atter 211, 1940, Serial No. 2 2,106 2 Claims. (01. 20 l) The present invention is designed to strengthen or splice poles such as telegraph, telephone and similar poles. Ordinarily such poles rot or become weak adjacent to the surface of the ground leaving a comparatively solid part in the ground with a comparatively solid part above the ground. The common practice has beento provide a stub pole long enough to extend into the ground some distance and to bind this pole by wire or other means with the pole above the ground. This manner of salvaging poles in use is more or less expensive and more or less limited as to life.

In the present invention these reinforcing members are extended along the face of the pole, one or more of such members being used. These members are such that without excavation they may be driven into the ground to the distance desired. These members are clamped to the pole by supporting bands. Preferably these bands extend below and above. the weak spot and are so arranged that they may be used with a single or plural set of reinforcement members and may offset the member so as to extend the splice or reinforcement to equalize the action on the members and provide a convenient means by means of which the clamps may be arranged above and below the ground level.

The invention also contemplates an improved method of securing the band and the arrangement also contemplates extending the members to points above and below ground level and in securing the pole both above and below the ground level. Features and details of themvention will appear from the specification and claims.

Preferred embodiments of the invention are illustrated in the accompanying drawings as follows:

Fig. 1 shows a side elevation of a pole having the reinforcement in place thereon.

Fig 2 an elevation of a single reinforcing member with a band in place therein.

Fig 3 a section on the line 3-3 in Fig 1.

Fig. 4 a similar section showing but one reinforcing member.

Fig. 5 a perspective view of one of the clamping bands.

Fig. 6 an alternative arrangement of the reinforcing members. i

l marks the pole, 22 the ground level, 3 the reinforcing members, these members being of T- shape with a web 4 engaging the pole, the web edges 5. An outstanding web G braces and is formed integrally with the web 4.

The reinforcing member is sharpened at the I bottom 1 and has a block 1a by means of which it may be driven into the ground.

The webs 6 have the slots 8 which are adapted to receive the clamping bandll. The clamping band has the out-turned lip ll] which, when in place, stems through the slot 8 with the lip at the opposite side of the web 6 from the adjoining band. The band has perforations l l and a clamping bolt l2 has an inturned portion extending through the openings H, the inturned portion terminating in a head l3 within the band. The clamping bolt [2 extends through an opening 14 in the lip l0 and through an outwardly extending slot or opening l5 in the web 5. As shown, this slot extends from the slot 8 but it is not necessary that these be joined, this being ordinarily for convenience in manufacture.

When a plurality of the members are used but one clamping bolt is required, the band being threaded through the slots 8 permitting the arrangement of the reinforcement, members as may be most desirable along the pole. The band permits the direct positioning of the web 4 on the surface of the pole and has no tendency by reason of plural fastening members of cocking the reinforcing members regardless of how many may be used.

The structure is particularly desirable in that a clamp may be put in place around the pole with the reinforcing member above the ground level and carried down as the reinforcing member is driven into the ground. Thus the clamping band may be carried below the ground level as indicated in the band just below the ground level in Fig. 1. Ordinarily a small excavation deep enough to provide clearance for the band is provided before putting in the reinforcing members. This facilitates placing the band and also setting up the single bolt for the entire band may be tightened up.

The structure also provides for a plural banding of the member above and below the ground level so that the pole is practically renewed regardless of any strength in the pole at the ground level and regardless of the quality of the ground in which the member is forced.

It may be desirable to provide a bolt ll extending through the pole and a perforation l8 in the reinforcement member preventing the working up or out of the ground of the reinforcing member.

It may also be desirable to provide an offsetare in register so that the band may be put in place.

The manner of uniting the ends oi the band is in itself a desirable feature and is adapted for use in other relations.

What I claim as new is:

1. In a pole reinforcement device the combination of a reinforcement member adapted to extend along and in engagement with the pole having a transverse opening therein, a band extending through the opening and having a lip 20 engaging the member, the lip of the band having a transverse opening and a connection secured to the opposite end of the band and extending through the opening in the lip and the member and exerting a clamping pull on the band.

2. In a pole reinforcement device, the combi nation of a reinforcing member adapted to extend along the pole, said member being substantially T-shaped with one web of the T in engagement with the pole, the other web portion of the T having a rtansverse opening therein, a band extending through the opening and having .a lip engaging the last mentioned Web portion, the

lip of the band having a transverse opening and a connection secured to the opposite end of the band and extending through the opening in the
